Hello Every Body,
Wish u very happy new Year.
I am still stucked in usb console in u-boot.
I implemented usb controller driver inside drivers/usb/ for s3c2440 from
open moko site and applied the changes in the u-boot required for
usbdcore_s3c2440.c.And in the udc_init() function i added the gpio
configuration as per usb device in my smdk2440 board.
But still the interrupt is not being generating yet when i am connecting the
cable from host to target..According to open moko,they added a small piece
of code inside cpu/arm920t/interrupt.c i.e
void s3c2440_irq(void)
{
printf("\ns3c2440_irq\n");
S3C24X0_INTERRUPT * irq = S3C24X0_GetBase_INTERRUPT();
u_int32_t intpnd = irq->INTPND;
#ifdef CONFIG_USB_DEVICE
if (intpnd & BIT_USBD) {
s3c2440_udc_irq();
irq->SRCPND = BIT_USBD;
irq->INTPND = BIT_USBD;
}
#endif /* USB_DEVICE */
}
And calling the function inside include/common.h as
#define ARM920_IRQ_CALLBACK s3c2440_irq
The "ARM920_IRQ_CALLBACK" macro is being called inside
cpu/arm920t/interrupts.c in do_irq() function as
#if defined (ARM920_IRQ_CALLBACK)
ARM920_IRQ_CALLBACK();
All the above i implemented ,but still i am not able to go next step.
So pls guide me further since m new to this usb
And one more question,did any body has done this usb console wrt smdk2440?
Thanks in advance
Arjun
